How often should the Freon in a new car's air conditioning be replaced?

As long as there is no leakage, the Freon in a car's air conditioning system can generally last the lifetime of the vehicle without needing replenishment. When Freon leakage occurs, it is essential not only to identify the cause of the leakage but also to promptly replenish the missing Freon. Below are the steps for adding Freon: 1. Before adding refrigerant, turn on the air conditioning switch and use a vacuum pump to create a vacuum. 2. Only after the vacuum process is complete can the refrigerant be added. Based on the maximum refrigerant capacity specified for the vehicle's air conditioning system, set the filling capacity, time, and type on the refrigerant recovery and charging machine. Once confirmed, the machine will automatically begin adding the refrigerant.
The refrigerant (Freon) in a new car's air conditioning system doesn't actually need to be replaced at fixed intervals. Based on my years of driving experience, I've found that AC systems are designed to be very airtight. Refrigerants like R134a typically don't deplete or leak on their own, and can last a full decade under normal use. For the first few years of a new car, you really don't need to worry about this at all. Only if you notice weaker cooling performance or less cold airflow might there be a leak requiring refrigerant recharge. I recommend checking vent temperatures yourself each summer and keeping the AC filter clean to avoid unnecessary strain. During routine maintenance, have technicians casually check system pressure - don't blindly follow recommendations for regular refrigerant replacement, as it wastes money and harms the environment. Modern cars use eco-friendly refrigerants with better sealing - just drive carefully to avoid collisions, and with proper care, your AC can last a remarkably long time.
